Fitzroy Minerals Inc. has commenced a 750 line-kilometer mobile magnetotelluric heliborne survey at its Caballos Copper Project in Valparaiso, Chile. The survey, conducted by Expert Geophysics Surveys Inc., is scheduled to cover the entire project area within two days, with interpreted results anticipated in March 2026. This advanced geophysical work represents a significant step in the company's exploration strategy for the copper-focused asset.
MobileMT technology is recognized for its ability to identify subsurface geologic structures, alteration halos, and contrasting lithologies. The survey will be complemented by VLF-EM data, which enhances resolution of shallow electromagnetic features. According to the company, combining these methods should enable the identification of deep-seated faults, lithological contacts, and structures controlling mineral systems from surface to depths of approximately 1 to 2 kilometers, depending on local geology conductivity.
Merlin Marr-Johnson, President and CEO of Fitzroy Minerals, stated that the MobileMT data is expected to generate a three-dimensional image of the Caballos Project area, including areas beneath younger volcanic rocks to the east. The company hopes the survey will assist in tracing the outline of mineralized breccias already intersected through drilling and help vector toward the origin of these breccias, which contain clasts of mineralized porphyry rocks. Marr-Johnson noted that MobileMT is particularly effective at identifying electrically conductive sulphides potentially linked to mineralized porphyry intrusive centers, as well as resistive bodies representative of intrusions.
The initiation of this survey has implications for the mining exploration sector, particularly in copper-rich regions like Chile. Advanced geophysical techniques like MobileMT can reduce exploration risk and costs by providing detailed subsurface mapping before committing to more expensive drilling programs. For investors and industry observers, the results expected in March 2026 could provide critical data points regarding the Caballos Project's potential scale and mineralization controls.
Fitzroy Minerals' broader portfolio includes the Buen Retiro Copper Project near Copiapo, Chile, the Polimet Gold-Copper-Silver project in Valparaiso, Chile, the Taquetren Gold Project in Rio Negro, Argentina, and the Caribou Project in British Columbia, Canada.
